OK, the 10,000 count Fairchild 7000A is specified for 0.01% + 1 count.  I got mine for $100, although you might struggle to find the same deal these days.  And it needed a bit of work too.

With 10M input resistance and 4 digits you need to wait quite a long time to see a drop. But with 6 or 7 digit DMM it's quite easily visible. Dave showed it in one of his videos.
